So there are many slam implementations out there for various sensors including GMapping, Hector, Cartographer, SLAM tool

Who is providing this transform in between this odom and map? - GMapping is responsible for map->odom. Note that GMap

Do you by any chance have a copy of visualization_msgs in your workspace? If you have delete it and use the one from you
